Summary: errno not available at setup.py time

Initial Comment:
This bug was introduced in Lib/os.py 1.59.

Distutils uses os._execvpe (indirectly) while building
extension modules, but the errno import can fail while
building the standard dynamically loadable modules that
come with Python.  This means that a clean build from
sources is not possible; the errno module must already
be available.

I can fix this by making the errno module built-in
statically, but would like approval before doing so,
since there may be other ways of dealing with this.  I
suspect errno is almost always used, however, so there
shouldn't be any problems with building it statically.

Argh! OK, make errno static. The alternative (hardcoding the
error values if errno can't be imported) seems unattractive.
